Description
In this talk we present a QFT study about the entanglement structure of the Hawking effect in evaporating scenarios. For this purpose, first we review the known concept of Hawking partners, as being the field modes that are entangled with, and thus purify, the thermal radiation. Then, we show how the definition of these partners can be generalized to any case where the temperature of the radiation increases over time according to the semiclassical evaporation process. Our explicit computation allows us to study the relative location of radiation and partner modes at past null infinity. Finally, we discuss some physical consequences of our results on the fate of quantum information in gravitational collapse.
